Big Idea: Observation and description of changes in the world around us are the first steps in finding and learning about patterns.
INV 5 Essential Question: How can a graphing calculator help me to discover relationships between variables?

A
1 Use your calculator to make a table for the equation y=3x

2 Copy part of the calculator’s table onto your paper

3 Use your table to find y if x=5

If x=5, y=15


B
1 Use your calculator to make a table for the equation y=0.5x+2

3 Use your table to find y if x=5
If x=5, y=4.5

5.2 Follow-Up

1 Use your calculator to make a table for the equation y=3x. Describe the graph
The graph is diagonal and pretty steep

2 Use your calculator to make a graph for the equation y=0.5x+2. Describe the graph
The graph is not steep, it's closer to being flat. it starts at 2 in the third quadrant, goes through the first, ends in second

3 How do graphs 1 and 2 compare
The Y=3x graph is steeper than Y=0.5+2

4 How would you make a graph for the equations y=3x and y=0.5x+2

I would first make a table of the information then create a graph out of it
